NASA said the capsule will depart the International Space Station early Tuesday morning instead of Monday.

Officials said the extra day will not affect science samples scheduled to return home in the capsule.

Station astronauts Tom Marshburn and Chris Hadfield are scheduled to maneuver the station’s robotic arm to release Dragon at 7:06 a.m. Tuesday.

Loaded with nearly 2,700 pounds of equipment and science experiment samples, the spacecraft is expected to splash down around 12:36 p.m. in the Pacific Ocean west of Baja, California.

Since the shuttle’s retirement in 2011, Dragon is the only vehicle able to return significant amounts of station cargo to Earth. The Dragon delivered about a ton of cargo to the station when it arrived March 3.
